Age of Empires II description

The * indicates that the civilization can fully upgrade their Bombard Cannons, i.e. gets Siege Engineers. Faith and Heresy are not taken into account because they only contribute to their combat strength in a very situational manner.

The ^ indicates that the civilization has at least one civilization or team bonus or a unique technology that benefits the combat strength of the Bombard Cannon.

The - indicates that the civilization had the unit in previous versions of the game but currently does not.

The Bombard Cannon is very powerful. It outranges all ranged buildings apart from Teutonic Castles, Korean towers, and Turkish Bombard Towers. A group of Bombard Cannons can effectively destroy a town in a matter of minutes, provided that they are adequately protected. Bombard Cannons are a powerful counter to siege units like Scorpions and Onagers, and can be effectively used against enemy ships and archers, but they are weak against non-ranged units, particularly Knights. They are also a great counter to Trebuchets, but should be moving while dealing with them in order not to be hit. Like Mangonels, Bombard Cannons have friendly splash damage and must be used with caution.

Comparison to the Trebuchet[]

The Bombard Cannon and Trebuchet are the longest ranged and most expensive siege weapons in the game. The Bombard Cannon is more maneuverable than the Trebuchet, as it does not require the packing and unpacking that are characteristic of the Trebuchet. However, Trebuchets are slightly cheaper, costing -25 gold and wood than Bombard Cannons (except for the Italians and Portuguese, who get a discount for them) and are available to every civilization, unlike Bombard Cannons, which are only available to some civilizations. Trebuchets are also more resilient, especially to ranged attackers, and can be used to destroy trees.

Comparing their attacks, Bombard Cannons are more accurate and deal splash damage against units, but have shorter range and can damage friendly units. They deal significantly less damage to their targets than Trebuchets, but fire faster and with much faster projectiles. Overall, Bombard Cannons are superior to Trebuchets in terms of versatility as they are effective against both buildings and units, but the Trebuchet's greater range and attack are unrivaled when it comes to taking down enemy buildings.

There are two heroes in the game with the appearance of a Bombard Cannon:


  • Although the Chinese invented the cannon in real life, their in-game civilization does not have access to it for balance purposes.
    • In the scenario Into China, the Mongols can capture Bombard Cannons from the Chinese Engineers, and the AI script for the Jin instructs them to build cannons despite being Chinese, implying that the civilization had access to them during development.
  • In terms of gold, wood, and raw resources, the Bombard Cannon is the most expensive unit in the game; the latter two only since Rise of the Rajas, because the Siege Tower was made cheaper.
  • Before The African Kingdoms was released, the Bombard Cannon was the only siege weapon that was created at the Siege Workshop that had no upgrade. In The African Kingdoms, the Siege Tower was added.
  • At release, all new civilizations introduced in The African Kingdoms and Rise of the Rajas had access to the Bombard Cannon. However, the Khmer lost access to the Bombard Cannon in update 36906, making them the only civilization that lost access to the Bombard Cannon.
  • Both civilizations introduced in Dawn of the Dukes have access to the Bombard Cannon.
  • Neither of the Central Asian civilizations have access to Bombard Cannon.


Gunpowder reached Europe from China by the thirteenth century and primitive cannons appeared first in the fourteenth century. Bombard cannons were large, ponderous, and dangerous to fire because the guns tended to break and because gunpowder was of uneven quality. They were used mainly in sieges where the time was available to set them up and fire them at a fixed target. By the fifteenth century, bombard cannons firing stone or iron shot were making castles obsolete. Cannons could bring down vertical stone walls quickly by firing shot at high velocity directly into the lower wall sections. Giant bombard cannons manned by European mercenaries were instrumental in the Turkish attack that finally captured Constantinople in 1453.
